In this step, the video to be skipped may be a video in which the story is mainly pushed by a role, such as a movie, a tv show, etc., and in one embodiment, the role information of the video to be skipped may be obtained by a face recognition algorithm, specifically, the face video may be performed on each video frame of the video to be skipped by the face recognition algorithm, so as to obtain the role information existing in each video frame of the video to be skipped. Or obtained through plot analysis, or obtained through manual identification.
S402: and determining the video frame with the role as a first type of video frame based on the role information for each role in the video to be skipped.
In this step, for example, it is assumed that a character a, a character b, and a character c exist in a certain video, and for the character a, the video frames including the character a include the 10 th video frame, the 15 th to 50 th video frames, and the 85 th to 100 th video frames, and then the video frames are taken as the first type video frame of the character a.
S403: and determining the storyline containing the character based on the first type video frames of the character and the time difference between the first type video frames.
In this step, the time difference between the first type video frames may be determined by the number of video frames existing between the first type video frames.
In one embodiment, when the time difference between two first-type video frames is greater than a preset threshold, the two first-type video frames are not in the same story line.
By adopting the story line dividing method provided by the embodiment of the invention, the video to be skipped can be obtained, the role information of the video to be skipped is determined, the role information is the role information existing in each video frame of the video to be skipped, the video frame with the role is determined to be used as the first type video frame according to each role existing in the video to be skipped and the story line containing the role is determined according to each role existing in the video to be skipped and the time difference between each first type video frame and each first type video frame, and the story line of the video to be skipped is divided according to the role information, so that each story line in the video to be skipped can be efficiently and accurately determined.
In one embodiment, in order to more accurately divide the story request, after the story line is divided for a single character in the above embodiment, the story lines can be further processed. For example, the storyline of the video to be skipped may be synthetically separated based on the storyline divided by each role, or the divided storyline may be further adjusted by combining the background, music and the like corresponding to the storyline after the storyline is separated, for example, a plurality of storylines under the same background music may be used as the same storyline.
In an embodiment, the step S403 may be specifically implemented by using the following story line determination method, as shown in fig. 5, including:
s501: and determining a first video frame of the first type as a second video frame from the video frames of the first type, and determining a video frame of the first type with a time difference larger than a first preset threshold from the video frame of the first type in each non-first video frame of the first type as the second video frame.
In this step, illustratively, and for ease of understanding, a simplified video frame profile is given, as shown in fig. 6, where each box represents 1ms, there are first type video frames A, B, C, D, E, F and G, where a is the first type video frame, the time difference between a and B is 1ms, the time difference between B and C is 2ms, the time difference between C and D is 4ms, the time difference between D and E is 2ms, the time difference between E and F is 4ms, and the time difference between F and G is 2 ms.
If the first preset threshold is 3ms, A, D and F are determined as the second type of video frame.
S502: and determining the first type video frame with the time difference with the previous first type video frame not larger than a first preset threshold value and the time difference with the next first type video frame larger than the first preset threshold value from the first type video frames as a third type video frame.
In this step, as an example shown in the above step, the time difference between the first type video frame and the previous first type video frame is not greater than the first preset threshold value comprising B, C, E and G, and the first type video frame having the time difference between the first type video frame and the next first type video frame greater than the first preset threshold value comprises C and E, then C and E are determined to be the third type video frame.
S503: and determining the third type video frame with the time difference not less than a second preset threshold value with respect to each third type video frame as a storyline ending video frame.
In this step, in order to avoid too short duration of the storyline, a second preset threshold may be set.
Illustratively, in the example shown in the above step, the second preset threshold is 3ms, and in the example shown in the above step, it may be determined that the time difference between C and the previous second type video frame (a) is 3ms, and the time difference between E and the previous second type video frame (D) is 2ms, then C is determined as the storyline ending video frame.
S504: and determining the previous second-class video frame of each story line ending video frame as a story line starting video frame divided aiming at the target role.
In this step, in the example shown in the above step, if the previous second-type video frame of C is a, it is determined that a is the storyline start video frame.
S505: and aiming at each storyline starting video frame, determining the video content between the storyline starting video frame and the next storyline ending video frame as the storyline.
In this step, in the example shown in the above step, the video content (small squares of gray portions in fig. 6) between a and C is determined as the story line.
With the above-mentioned another storyline dividing method provided by the embodiment of the present invention, a first video frame of a first type may be determined from the first video frames as a second video frame, and a first video frame having a time difference with a previous video frame of the first type that is greater than a first preset threshold may be determined from the non-first video frames of the first type as the second video frame, and a first video frame having a time difference with a previous video frame of the first type that is not greater than the first preset threshold and having a time difference with a next video frame of the first type that is greater than the first preset threshold may be determined from the first video frames as a third video frame, and a third video frame having a time difference with a previous video frame of the second type that is not less than the second preset threshold may be determined for each third video frame as a storyline ending video frame, and determining the first second type video frame of each story line ending video frame as a story line starting video frame divided aiming at the target role, and determining the video content between the story line starting video frame and the next story line ending video frame as the story line aiming at each story line starting video frame.
